The API uses Fastify rate limiting on all routes.

• Limit values are configured via environment variables:
  • RATE_LIMIT_MAX
  • RATE_LIMIT_WINDOW
• Exceeded requests return:
  • 429 Too Many Requests
  • retryAfter (seconds) in response body

Publish queue retries

Publishing runs through BullMQ with retry policy:

• attempts = 3
• Exponential backoff:
  • 1st retry: 5s
  • 2nd retry: 10s
  • 3rd retry: 20s
